# Controlling video quality
<a name="video-quality"></a>

You can tune video quality in each output in an Elemental Live event. You tune the video quality by setting parameters that are in the output section of the event: in the relevant output group, choose an **Output**, choose a **Stream**, choose the **Video** tab, then open the **Advanced** section. 

The following list identifies the parameters that affect video quality. The list also specifies the section in this guide that describes the parameter.
